Cam Follower HI-Grade Tappet Set

A new super grade tappet (cam follower) has been manufactured to replace the no longer available Isky follower. The new follower is lighter than the original weighing only 43.2 grams vs. 48 grams for the original. This ultimate cam follower is designed to minimize lifter float normally seen in original cam followers which ultimately looses horsepower. Precision ground outside diameter with a smaller chamfered base to give more surface area for extra hi lift cams. Careful and tightly controlled manufacturing ensures best edge consistency, perfect chamfered radius on the base and walls for best rotation and movement. The side walls are also 70 thou taller to maintain maximum stability. Heat treated 3 times to a minimum hardness of 48 HRC / Generally around 52 HRC. Face chilled to a depth of 0.060"/0.177" and nitrided to TNPI before finish grinding for perfect sizing. In addition, these lifters have an oil drain hole, thus preventing oil from collecting in the lifter. This is currently the most robust lifter available for highly tuned engines.
